We all know the basic issues, like **** diplomacy, AI needing bucket loads of cheats to even stand a chance and so on.
But scripting the AI to target the player against all odds to provide some level on challenge is just idiotic ; and i am not even talking about the "tested" chaos invasion.
I had a game yesterday where i joined a war against Durthu while playing the dwarfs bc i wanted to get military access across the border princes . Some turns later i saw Durthu ( down to the home province only at that point and 1 1/2 stacks ) with his full stack start to make his way down the map.
He ignored all the unguarded enemy settlements along the way and for ~10 turns went all the way to the badlands where he razed one of my small towns and then proceeded to wait around since all the others around it were too much for his stack. Not to mention he left his only province unguarded with 3 enemy factions around just to raze a town half way across the world owned by a faction with whom he never fought one battle and who was 20 power ranks above him......
GG CA, elite level scripting, i could write something in bash shell to do this as well.
